LG debuts 'world’s largest' OLED display

LG has shown off two of the largest OLED displays in the world at South Korea’s Incheon International Airport. In creating the installation, LG worked closely with French design firm Wilmotte & Associés to develop the structures which hang above the main terminal of the airport. Each sign is composed of 140 55-in curved OLED panels, resulting in displays that stand 13 metres high and 8 metres across, equivalent to three large-sized shipping containers.

The two curved displays will feature a variety of content to demonstrate the capabilities of OLED technology, such as fireworks set against a night sky. And because every pixel in an OLED display emits its own light, there is no need for heavy LED backlighting, making both of the airport displays light and flexible which allows them to hang from the ceiling with minimal support. “These OLED displays perfectly complement the advanced technology that our airport has become known for,” said Park Wan-su, president and CEO at Incheon International Airport. “We are always eager to showcase to the millions of travellers every year the cutting-edge technology that originates from Korea. OLED is a prime example of that.” “While the world’s largest OLED sign is certainly something to be proud of, we are more excited about the opportunity to introduce travellers from across the world to the magic of OLED,” said Ro Se-yong, senior vice president and head of business-to-business solutions at LG Electronics. “The benefits of OLED technology can only be viewed, they cannot be described with mere words.” Contact Details and Archive...LG Electronics Inc, Source: InAVate

Displays maintain resolution when stretched

Displays that can stretch while still maintaining pixel resolution could be possible after two researchers at a Korean University detailed research into a new composite for an LED display. The findings, reported on SPIE (society for optics and photonics), detail a technique that uses a "hidden pixel structure" to ensure pixels are not stretched or strained when the display is altered.

Researchers Yongtaek Hong and Sangwoo Kim from Seoul National University developed two types of stretchable electrodes. Pixels hidden in display only turn on when the array is stretched and thereby maintain the original pixel density. The researchers wrote: “To enable resolution-sustainable stretchable display technology in real devices, the use of the hidden pixel structure and negatively strain-dependent nickel composite electrodes seems highly promising.  “Our results have shown that we can easily make appropriate electrode patterns for LED arrays by using a patterned magnetic field. Our next step will be to show that this method can provide a platform technology for 2D and high-resolution pixel arrays.  “Our approach and concept could be one of the key enabling technologies for future stretchable high-performance electronic display devices. To make a practical display using this concept, we now need to improve the operational stability of the composite electrodes and develop a high-resolution patterning method for the composite based on the patterned magnetic field.” Source: InAVate
